I guess that means that every black pixel has fully lighted pixels hiding behind it? What if a particular pixel was "almost black? Are there "halfway states" of the polarised filtration? I wonder what colour would be the lowest overall power consumption for a desktop/background. And whats the difference between a traditional LCD screen and the newer LED LCD screens? - I'm guessing that the older LCD screens must keep the light (fluoro) on all the time and black out pixels as required, but I wonder if the LED ones have a single white LED at each pixel location - allowing dimming to be controlled on a "per pixel" level?

LED monitors are still LCD displays. But they use LED lights instead of cold cathode fluorescent tubes to create the backlighting. So they are more energy-efficient.

If you want to see an interesting effect, hold a pair of anti-glare sunglasses in front of your LCD monitor and slowly rotate them.

Since LED lights are basically either on or off, I wonder if it's the latter?

That's not really true though. You can use a POT or resistors to vary the brightness of a plain old LED just fine. I know because I did some automotive gauge cluster lighting, and turned down the brightness of some LED backlighting with resistors so it didn't blind me at night. I would imagine you're controlling the backlight brightness with either setup._________________"In a world that exists without walls and fences, who needs Windows and Gates?"

For best image, I set CONTRAST at 90 to 95% (which usually gives a good black, depending on raster), and then adjust BRIGHTNESS to 50% or less, depending on ambient light. If there is color flare, like in red or orange, I will tweak the CONTRAST down until flare disappears, and then readjust BRIGHTNESS if necessary.

Is this opposite to recommended adjustment procedure? And, does setting CONTRAST so high shorten the life of the monitor?Last edited by nubc on Tue 27 Nov 2012, 14:12; edited 3 times in total

You guys got me thinking and playing around with my monitor settings. Mine has separate adjustments for backlight level and brightness, so now I'm thoroughly confused. I just use the lowest brightness and backlight setting I can get away with and still be viewable so as not to burn my eyes out. The stock setting kills me. Still don't know the technical difference, but apparently it does adjust something to do with the color producing parts as well as the backlight. So if you have a monitor that has just one setting, who knows which one you're adjusting? Maybe a mix of both?

My computer and monitor are hooked up to a UPS that shows power consumption. I may check it out with full on brightness and backlighting and compare it to full dark and as low as the light will go to see the real difference._________________"In a world that exists without walls and fences, who needs Windows and Gates?"

Keep in mind these figures are purely for giggles. The extreme ends of the spectrum are unusable, so you're getting info on an amount of backlighting that I'm confident no human eyes could stand for long, as well as brightness that is so washed out it's unusable. It's just for reference.

At my personal setting: BL 22, Bright 43, Con 50
PC and 26" 1920x1080 LED lit: 96 watts total with the PC idling on the desktop with a nice balance of darks, lights, and plenty of contrast needed to show the details.

As you can see, whatever the Brightness control is adjusting seems to do pretty much nothing to power consumption on my setup, while the backlight seems to be drawing around 36 watts nearly all on its own when set to max. I believe it too. It's CRAZY bright.

I guess the thread is thoroughly derailed now. _________________"In a world that exists without walls and fences, who needs Windows and Gates?"

Interesting though. I have a passion for low energy devices as some of my gear is run in a workshop that has no mains power - only solar. I think it would be great to have a topic that discussed low power computing. There are so many neat devices coming on stream now. One of my projects is a eeepc that is charged/run by solar panels. (It is VERY economical after sundown - it draws no power at all!)

Yeah, it'd be a good topic for this forum now that so many people are trying to save energy for environmental as well as financial reasons.

I installed OpenSUSE Edu-life yesterday, and something went wrong with the configuration so that when I boot up I get a root terminal instead of a desktop / window manager. I have to enter at the terminal which of KDE or Gnome I want before I can get a desktop session. Once you get past that though, it's pretty good._________________Acer Aspire M1610 (Core 2 Duo, 2.3 GHz), 3 GB of RAM, 320 GB hard drive running OpenSUSE 13.2 Edu-Life, Sparky 4.0 RC1, Neptune 4.3, Absolute 14.11, Korora 21 Mate, Vector 7.1 Light 64-bit, LXLE 14.04.2, Puppy Tahr 6.02 Mate and Puppy Precise 5.7.1 Large.Last edited by Colonel Panic on Thu 29 Nov 2012, 11:55; edited 1 time in total

It doesn't have Synaptic or Software Center? If not, Synaptic would be my first installed app. Sky's the limit from there._________________"In a world that exists without walls and fences, who needs Windows and Gates?"
